BLACK TEA CLASSES
What is black tea?
Black tea is a mildly stimulating drink that is obtained from the leaves of the tea plant (Camellia sinensis).
Black tea differs from other types of tea because it has undergone a process of complete oxidation.
During this process, the polyphenols of the leaves have been oxidized, causing darkening of the leaves. Due to this type of tea being very dark, it is called black tea. It is also known as pseudo – fermented tea or fermented.
Black tea is as astringent tea because polyphenols have become theaflavins and thearubigins, giving the infusion a reddish color and a bitter taste.

Black tea, A fermented tea?
Popularly there is widespread belief that black tea is a fermented tea.
However, the process of making black tea is not really a fermentation, since there is not any microorganism (bacteria) involved. Recently it is wanted to change the term by aeration because it is considered to be more correct.
This change of terms is also due to the fact that, in Muslim countries, it is believed that black tea might contain alcohol because it is a ” fermented ” plant, something which is not true.
Benefits of black tea
Black tea tea acts as a moderately stimulating tea, reason why it is usually taken as the first thing in the morning (as in the popular English Breakfast).

In addition, black tea contains a certain amount of tannins, which help regulate the absorption of caffeine so its effect are not as immediate. For this reason, it is moderately stimulant, without the power of coffee.
During processing, its polyphenols are oxidized, so that its antioxidant capacity will be lower than green tea. However, it still retains some of its active ingredients (catechins), so that, although less effective than green tea, it has antioxidant properties to reduce cholesterol , prevent arteriosclerosis and Parkinson’s.
Another feature of black teas lies in its composition. It contains theaflavins and thearubigins, astringent substances derived from the oxidation of tea polyphenols. They bring the strong characteristic flavor of black tea. They are also responsible for the red or orange tinge and astringency of black tea infusions.
